The camera is manufactured with a Sony 3-megapixel CMOS sensor by Point Grey, and will be presented at the Intel Developers Forum this week. The USB-IF—which controls the SuperSpeed USB certification process—says that they expect USB 3.0 devices to arrive to the market at the beginning of 2010. [Engadget and Electronista]
